class ExampleStackRoutes {
  static const String firstRoute = 'firstRoute';
  static const String secondRoute = 'secondRoute';
}

class ExampleStackRouter extends StatelessWidget {
  const ExampleStackRouter({
    Key? key,
  }) : super(key: key);

  @override
  build(context) {
    return StackRouter(
